3. Terms

Electricity cost (10 years): The electricity cost of rice cooker in 10 years, according to the annual electricity consumption below. The electricity price is set at 0.5 RMB per kWh. Unit: RMB.

Annual electricity consumption: The electricity consumed by rice cooker within one year. The typical daily electricity consumption of rice cooker is set as the electricity consumed by heating 80% rated volume water of the cooker from 25℃ to 95℃ and the electricity consumed on warming mood for half an hour. Annual electricity consumption is 365 days’ consumption, Unit: kWh.

Heat efficiency value: Heat efficiency value is the ratio between the energy certain water absorbed in certain time to the electricity energy consumed in the same time. Unit: %.

Warming power: The electricity energy consumed for the rice cooker working for an hour on warming mood. Unit: W·h.

Volume: The volume of the inside cooking space of the rice cooker. Unit: L.

National energy efficiency grade: The mandatory grading system for energy using products to disclose the energy performance to the consumers. Grade 5 is the minimum energy efficiency requirement for the market access and Grade 1 is the best for the monitors.

For rice cookers with metal inner pots, the MEPS is the requirement of grade 4. For non-metal inner pot rice cookers, the MEPS is the requirement of grade 5.
